Study of the stress-strained state of shallow shells and plates on the basis of the second approximation shift theory

摘要

The orthotropic layered gently sloping shells and plates are researched on the basic of the refined theory of the second approximation, where the lateral shears are distributed according to the law of the fourth power parabola. It is shown, that the theory of second approximation has more wide area of using as compared with the theory of first approximation, both physico-mechanical and geometrical parameters of layered constructions.
